brought home by Mr. Goodfellow and have been most 

 generously presented to the Museum by Mr. Brook. They 

 include the types and co-types of five new species and 

 subspecies described recently by Mr. Chubb (Bull. B. O. C. 

 xxxvi. 1916, pp. 46-47), viz., Asia galapagoensis aquatorialis, 

 Ciccaba albitarse goodfelloivi. Pyriglena castanopterus, Gral- 

 laria nuchalis obsoleta, and Automolus brooki, and numerous 

 other rare forms most of which were wanting or previously 

 very imperfectly represented in the collection. 



We should also like to draw the attention of our readers 

 and members to the series of exiiibition cases in the Bird- 

 Gallery of the ]\Iuseum. For some years past these cases 

 have been gradually rearranged and reuovated. New speci- 

 mens freshly mounted have been substituted for the old 

 ones, and the whole collection rendered more instructive by 

 the provision of maps and additional explanatory labels. 



Cases 67-72 have recently been completed in this manner 

 and there remain only twelve more to be taken in hand. 

 It is most important that these should be completed, and it 

 is to be hoped that the Trustees of the Museum will see 

 their way to provide the necessary funds to complete the 

 ■work.
